Explore the problems often encountered by fiber laser cutting machine!

First，one Abnormal sparks often occur when cutting sheet carbon steel

We know that when laser cutting sheet carbon steel, normally the spark bundle is long, flat, and the slit is less, and the abnormal spark will affect the smoothness and processing quality of the workpiece cutting surface. If other parameters are normal, the following conditions should be considered:

1.one Laser cutting head nozzle loss is serious, to replace the old nozzle in time;

2.In the case of no new nozzle replacement, the cutting auxiliary gas pressure should be increased;

3.If the thread at the connection between the nozzle and the laser cutting head is loose, the laser cutting should be immediately suspended, the laser cutting head connection status should be checked, and the thread should be good again.

Second，two The laser did not cut completely

1.one The choice of laser nozzle does not match the thickness of the processed plate, replace the nozzle or process the plate;

2.Laser cutting line speed is too fast, the need for operational control to reduce the line speed.
